A MYSTERY creature that eats geese in the blink of an eye has returned to haunt murky waters around the £9billion Olympic Park.

Six years ago there were fears a crocodile was stalking big birds as they were sucked from a river’s surface – never to be seen again.

Some experts then suggested a giant turtle was the culprit, but before the riddle could be solved the killer monster apparently vanished.

Now it seems to be back. Mike Wells, a boat-dweller living on the River Lea in East London, was last week sitting on his barge with a friend when their peace was shattered.

Mike said: “We were just passing the time of day looking at a Canada goose 30 yards away, but then it just suddenly disappeared.

“It went down vertically. There wasn’t any hesitation, it went straight down. It didn’t come back up. My friend and I looked at each other slack-jawed.

“Being a river person, I pieced together what we’d seen in seconds. The goose was prey to something.

“A Canada goose is not a small bird. They weigh about 16lb, so whatever took it was also large.”

Searching for answers, Mike then came across several similar incidents from 2005 when there was speculation a crocodile might have taken up residence in the River Lea.

Mike now wants the Environment Agency to investigate. A campaigner against the 2012 Olympics’ impact on East London, he also joked: “My hope is Lord Coe will fall in and the creature will have him for lunch.”
